  - the Special:DeletedContributions page allows remote attackers to determine if an IP is autoblocked via the 'Change block' text.

  - the ApiBase::getWatchlistUser function does not perform token comparison in constant time,
  which allows remote attackers to guess the watchlist token and bypass CSRF protection via a timing attack.

  - Cross-site scripting (XSS) vulnerability in thumb.php via the rel404 parameter, which is not properly handled in an error page.

  - Cross-site scripting (XSS) vulnerability in thumb.php via the f parameter, which is not properly handled in an error page, related to 'ForeignAPI images.'");
